Hairy root cultures of Nicotiana tabacum were set up by excised root tips with Agrobacterium rhizogenes. The successful transformation was confirmed by analyzing rolC and virC genes using polymerase chain reaction (PCR). Hairy root cultures were employed to study the formation of pyridine alkaloids,

Although secondary metabolism in Nicotiana tabacum (L.) (tobacco) is rather well studied, many molecular aspects of the biosynthetic pathways and their regulation remain to be disclosed, even for prominent compounds such as nicotine and other pyridine alkaloids. To identify players in tobacco
A MDR transporter contributes to the different extracellular production of sesquiterpene pyridine alkaloids between adventitious root and hairy root liquid cultures of Tripterygium wilfordii Hook.f.

UNASSIGNED
TwMDR1 transports sesquiterpene pyridine alkaloids, wilforine and wilforgine, into the hairy roots of T. wilfordii Hook.f. resulting in low secretion ratio of alkaloids. Hairy roots (HRs) exhibit high growth rate and biochemical and genetic stability. However, varying secondary

Nicotiana glauca (Argentinean tree tobacco) is atypical within the genus Nicotiana, accumulating predominantly anabasine rather than nicotine and/or nornicotine as the main component of its leaf pyridine alkaloid fraction. The current study examines the role of the A622 gene from N. glauca (NgA622)
Root-to-shoot translocation of alkaloids is dominantly suppressed in Nicotiana alata.

In tobacco (Nicotiana tabacum), nicotine and related pyridine alkaloids are produced in the root, and then transported to the aerial parts where these toxic chemicals function as part of chemical defense against insect herbivory. Although a few tobacco transporters have been recently reported to

In this study, we determined the pyridine alkaloid content (nicotine, nornicotine, anabasine, anatabine, cotinine, and myosmine) of 58 species and 2 subspecies of the Nicotiana genus by ultra-high-performance liquid chromatography coupled with mass spectrometry. We observed clear correlation between

Levels of pyridine alkaloids were measured in 18 tobacco, Nicotiana tabacum L., entries from three parental isolines ('NC 95', 'SC 58', and 'Coker 139'), grown at Tifton, GA, Florence, SC, and Oxford, NC, in 1991. Levels of alkaloids in bud leaves (first fully unfolded leaf below the apical leaf

We present two cases of rare human poisoning in one family following ingestion of cooked leaves from the tobacco tree plant, Nicotiana glauca. The toxic principle of N. glauca, anabasine (C10H14N2), is a small pyridine alkaloid, similar in both structure and effects to nicotine, but appears to be

Nicotine, the most abundant pyridine alkaloid in cultivated tobacco (Nicotiana tabacum L.), is a potent inhibitor of insect and animal herbivory and a neurostimulator of human brain function. Nicotine biosynthesis is controlled developmentally and can be induced by abiotic and biotic

In plants, secondary metabolites play important roles in adaptation to the environment. Nicotine, a pyridine alkaloid in Nicotiana tabacum, functions as chemical barrier against herbivores. Nicotine produced in the root undergoes long-distance transport and accumulates mainly in the leaves. Since
Antisense-mediated down-regulation of putrescine N-methyltransferase activity in transgenic Nicotiana tabacum L. can lead to elevated levels of anatabine at the expense of nicotine.

Nicotiana tabacum L. produces a number of pyridine alkaloids, with nicotine representing the major component and anatabine comprising most of the remainder of the alkaloid fraction. An antisense approach was used here to down-regulate activity of the important enzyme putrescine N-methyltransferase
